Specification of Letters Patent.

Patented Sept. 12, 1916.

Application filed October 7, 1915. Serial No. 54,579.

To all whom it may concern Be it known that I, WILLIAM C. BRUMDER, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a certain new and useful Improvement in Type- Writers, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to typewriters, and has for its object the provision of a type or other character writer of this character in which the operation may be controlled by the selective operation of a very much smaller number of control elements than the ultimate number of letters or characters which the device may print or otherwise set up.

In the preferred form of my invention, I employ a plurality of character controlling elements whose selections in different combinations-or in different order or in amount of movement controls the ultimate selection of a given character in accordance therewith. In this application I show one specific form of such device constructed in accordance with my invention, and in this particular device I have five character selecting bars which are all associated or placed'in juxtaposition to a number of elements corresponding to the characters 'de sired for selection. These character selecting bars are movable and by the selection for movement of one or more of these character selecting bars any one of a great plurality of characters may be selected; even though as in the specific device herein illustrated each bar is designed to move but one step. I will explain this specific form of carrying out my invention more in detail by referring to the accompanying drawings illustrating said specific embodiment, in which- 2 Figure 1 is a top plan View of a device constructed in accordance with my invention; Figs. 2, 3 and 4 are longitudinal sectionalviews respectively taken between various selecting bars;'Figs. 5, 6, 7 8 and 9 are side views respectively of the selecting bars; Fig. 10 is a bottom View showing the transversely mounted character elements; Fig. 11 shows one of the character elements in detail together with the circuit it conthe corresponding bar one step.

trols; Fig. 12 is a detail sectional view on line a-a of Fig. 6, and Fig. 13 is a detail sectional view on line bb of Fig. 7.

My invention contemplates the provision of a suitable base plate 1 upon which seven keys respectively 2, 3, 4, 5, 6, 7 and 8 are pivotally mounted. These keys 2, 3, 4, 5 and 6 are respectfully pivotally associated with selecting bars 9, 10, 11, 12 and 13, which selecting bars as shown more clearly in Figs. 12 and 13 consist of a metallic strip 14 carrying an insulating rib 15, which insulating rib as shown more clearly in Figs. 2 to 9 has teeth, some of which teeth have metallic caps 16. These bars 9 to 13 slide horizontally over the base plate '1 in answer to the movement of the buttons 2 to 6 inclusive. The movement of any button or" key moves Now by the selection of one or more bars it is possible to determine the selection of any one of a plurality of characters, and this selection is due to the selective placing of the metallic cap 16 upon some of the teeth, whereas other teeth, designated by 16*, are merely extensions of the insulating strip 16. These bars cooperate with type elements 17 to 44 inclusive, each type element having a peculiar construction to cotiperate with the teeth of the bars, and each element when properly controlled serving to cause the 210 tuation of the character corresponding to that element. This will be more readily understood by an inspection of Fig. 11- where the element 42 is shown. This element in the particular construction herein disclosed consists of a strip 45 of insulating material having at its extremities conducting pins 46 and 47 by virtue of which it is pivotally mounted in side frames 48, 49, (referring to Fig. 1). The side frame 48 is metallic so that all of the pins 46 contact with it and one binding post 50 is used to extend the circuit from this side frame 48 by means of conductor 51 to a battery 52. .The other pins 47 are insulatingly mounted in the side frame 49, but are connected each to each to binding posts 53, from which binding posts conductors 54 may extend to relays 55, there being one relay for each type element, and each relay 55 controlling a particular type lever 56, which type lever may actuate suitable type or other character as in an ordinary typewriter. The other connected by means of conductor 57 with the other terminal of the relay 55, the con- I so ' V se ductor 57 being a common conductor, but conductor 54 being one of a plurality of individual conductors, one leading from eachtype element such as 18. These type elements 18 are hinged as stated and which have at various points on their lowermost extremity openings which are faced on the sides by contact strips 558, 58. These contact strips, referring. to [Fig 11, are serially included in a circuit extending from the pin 46 to the pin 47 It will be seen from this that no circuit can be completed through the type element 42 unless both of the contact devices 58 in this element are connected together. There being five bars, I may say that these are shown in the side view in Figs. 5 110 9 inclusive and are also respectively denominated by the Roman numerals I, II, III, IV, and V.

It will be seen by an inspection of Fig. 10 that the various elements 17 to 44 inclusive are provided with metallically faced openings 58 which are in definite rows, and these rows are also designated by the Roman numerals I, II, III, IV, and V, -so as to show which of the bars 9 to 13 cooperates with the particular row of openings 58 of these various type elements 17 to 44 inclusive. An inspection of Fig. 10 will show that so far as theelement 42 is concerned, it is necessary to move the bars corresponding to the Roman numerals III and IV one step in orderto close the circuit through this element 42. That corresponds to the bars 11 and 12. Thus a movement of the keys 4 and 5 tomove their respective bars one step would cause the closure of the circuit through the'type bar 42. The functions of'the teeth 16 are to tilt various of the elements 18 to 44 inclusive out of their vertical position by having these teeth en-' gage the unbroken lower face of said elements. It may be stated that these insulating teeth 16 can pass through the openings 58 without touchmg or 'moving the bars. Thus if we refer for instanceto Fig. 2 in which the bar 9 is shown in its normal position, and all of the elements are shown in their vertical position and thenassume the alternative position ofFig. 3, inwhich the bar 9 has been moved one space to the right, then it will be seen that this bar 9 (comparing, also column 1 of Figs. 5 and 10), has beginning at the left sixteen conducting teeth 16, and these may enter all of the metallically faced openings of the sixteen first type elements and consequently completing the circuits therethrough. The remaining,

teeth of bar 9 however are'required, and under these conditions would ush the remaining type elements 33 to 44 inclusive out vthose skilled in the art.

Letters Patent isz' 1. In a-device of the character describedof one step of the bar 9 however completes the circuit only through the element 17 as it will be apparent from an inspection of Fig. 10 that the remaining elements 19 to 32 inclusive require the closure of more than one metallically faced opening 58. The element 33 needs closure of but one metallically faced opening 58, but that would be due to a movement of the bar 10.

The combinations have been so worked out that but one of the elements 18 to 44 inclusive has its complete circuit closed with any given combination of the bars 9 to 13.

Inthose cases where there might be interference, the insulating teeth push those of the elements 18 to 44 1nclusive which might interfere out of the path as shown for instance in Figs. 3 and 4 so that there will not be a double type actuation. It is to be understood that the metallically headed teeth 16 may enter into themetallically faced openings 58 without moving them substantially out of their vertical alinement, and this of 'course can be done by a slight inclination of the faces or in any other suitable way which would permit positive withdrawal of these teeth without dragging these elements, along out of their neutral position; but contacts of course could be used if desired. It will be understood of course also that the arrangement can be such that illustrated. v

There are two additionalkeys 7 and 8 as shown in Fig. 1 and these are supposed to control additional circuits that may extend from the device of Fig. 1 to additional relays such as 55 which can be used for upper or lower case work so that three characters may be utilized upon each type lever 56 in accordance with ordinary typewriter printhe type elements are needed for the list, then the additional ones provided can be utilized for carriage return, spacing, and line adjustment purposes. It will of course be understood that further combinations can be secured by a change in-the sequence of ciples. Assuming that but twenty-six of operation of thebars so that the order. in

which theyare selected controls. a
